I have a couple of these DC motors
Which have an extended motor shaft that sticks out the back and is 1mm diameter.
I'm having trouble trying to think of the best way to attach an encoder disk to this shaft.
I thought of getting a custom wheel 3d printed and make the opening 0.9mm so it will be a tight fit. But I don't know if is just to small?
I also though of taking the encoder disks from a PC mouse and drilling a 1mm / 0.9mm but its the same problem but with the added difficultly of trying to drill a small hole on a small thing.
So I wondered if anyone knows a better way, or of a made disk to attach. As I just can't find anything for a 1mm shaft
